Which sequence of rigid transformations will map the preimage ΔABC onto image ΔA′B′C′ ?

a reflection across the x-axis, a translation 8 units right, and then a reflection across the x-axis

a translation 4 units down and 10 units to the right

a reflection across the line y = x followed by a rotation 90° counterclockwise

a rotation 180° clockwise followed by a reflection across the x-axis
